摘要:探讨了改变浆料配比中杨木化机浆的用量对配抄米黄书写纸颜色、物理强度等性能的影响。结果表明，随着浆料配比中杨木化机浆用量的不断增大，纸张的亮度降低，a*值变化规律不明显，b*值升高；纸张的松厚度有明显增加；纸张的抗张指数和耐破指数降低；纸张的灰分含量无明显变化。

Abstract:The properties of yellow writing paper were studied by changing the proportion of poplar APMP in paper furnish. These properties included L*a*b*, physical strength and ash content. The results revealed that the brightness decreased, a* kept stable, and b* increased by increasing the proportion of poplar APMP in paper furnish. The bulk of paper was significantly improved, both the tensile and burst indexes decreased. The change of ash content was insignificant.
